"My body immediately became afraid," Miller told CBC News. "I was so struck by the size of their heads and their jaws." She recorded it, she says, because she thought no one would believe her if she didn't. Animals will frequently venture out onto the highway, but she had never seen a wolf before, let alone two.
This pair, as the video shows, was sprinting at a full clip. Miller estimated that the wolves were running "between 40 and 50 [km/h]... It was fast." There are about 4,000 wolves in the Northwest Territories per 2013 numbers from the International Wolf Center, and they're mostly nocturnal animals, so seeing them in daylight on the highway was a rare sight.
